RevTech 6-Speed Overdrive Gear Sets with
Trapdoor and Bearings
These complete gear sets have close-ratio 2.94:1 first gears and
.893:1 overdrive sixth gears and come pre-assembled and ready
to bolt into the original equipment transmission cases on most
Big Twin models from 90-06. These kits benefit from all of the
advantages found in the complete RevTech 6-speed transmission assemblies but without the higher cost. They include all of
the parts found in the 6-speed gear sets as well as our RevTech
forged aluminum trap door for strength and durability. Having
the gear set pre-assembled to the trap door simplifies and
speeds up the installation. Each kit also includes a chrome decorative end cover faceplate that bolts to the clutch release cover
that features the distinctive RevTech 6-speed logo laser-etched
into its surface.

RevTech 6-Speed Overdrive Gear Sets
Customize gear ratios in RevTech 6-speed transmissions and gear
sets by selecting alternate first and sixth gears. The 3.21 ratio
first gear is the same ratio as the OEM first gear used since 1996
(and comparable to the 3.24 ratio used from 80-95 on domestic
models), while the .860 ratio sixth gear provides even lower
engine RPM at freeway speed.
3.21 ratio 1st gear set
.860 ratio 6th gear set
Note: Installation on 94-Up models with electronic speedometers will require speedometer recalibration. Use CC #310669 and special neutral switch (CC #30439) on
1998 and newer models. Also, when running an electronic speedo, the purchase of a
speedo pickup sensor plate (CC #30438) is required.
